The man, who has not been identified, jumped off the bridge about 2 a.m., prompting the West Springfield and Springfield fire departments to launch boats to find him.

Emergency personnel called off their search shortly after 3:45 a.m. About a half-hour later, a police office on patrol spotted the man, shirtless and wearing long pants, walking along Kings Highway near Sheridan Avenue, Capt. John Ferrarini said.

“It’s a little chilly that time of morning,” Ferrarini said, adding that the man was taken to Baystate Medical Center in Springfield for observation.

Initial reports stated that the man did not know how to swim, and Ferrarini said that family members reported he was not a strong swimmer.
